DVMEGA on a Raspberry PI using MMDVMhost software

Firmware not detected

Some people have issues with the “firmware not detected” message when run the
DVMEGA on a Raspberry PI uysing MMDVMhost software. I have made an simple
instruction to get your hardware platform run. I have test the instruction below on
Raspberry B+, V2 and V3. This is not an instruction how to install but just to check
your configuration.

Start with burn a new Western D-Star image on your SD card. This image can be
download from next location : http://www.westerndstar.co.uk/Downloads/DStarRepeater+ircDDB+Widget_Pi3.rar

Place you DVMEGA onto the Raspberry PI before you start the image the first time.
Do not load or install other software and do not change settings yet. The Western DStar
image comes with DVMEGA default pre-configured. Check first if the beacon
counter does count up.

If the beacon counter is counting you know your hardware platform is okay.
Before you install the MMDVMhost, stop the autostart of the D-Star repeater module.
– Start the Widget
MegaMMDVM2
– Set Starup repeater1 to “none”
MegaMMDVM3
– Press Save
MegaMMDVM4
– now power cycle your Raspberry PI. This is a very important step. The DVMEGA
has a auto protocol selector at start up. The DVMEGA is now running in D-Star mode
and has to be power cycled to enable the protocol selector again for MMDVMhost
later on.

When the Raspberry has restarted, check that only the ircDDB Gateway runs.

You can find more information on the ircDDB Gateway settings, under chapter
“Configuration ircDDB Gateway software” in next document :

Now we go to prepare the raspberry for MMDVMhost

– Open a terminal window
– Type “sudo apt-get install git” (git tool will be installed now)
– Type “git clone https://github.com/g4klx/MMDVMHost” (directory will be created and
all required files downloaded)
– When download is done go into the new created directory, Type “cd MMDVMHost”
– Your promt will be look like this : pi@raspberrypi:~/MMDVMHost $
– Then enter “make” (to compile the MMDVMHost software)
– When compilation is done you have to set your MMDVM.ini.

Type “sudo nano MMDVM.ini” , a working .ini looks like this :
